IMPROVEMENT lN APPARATUS FOR COOLING MINES.

' Specification forming part of Letters Patent No. 219,222, datedSeptember 2, 1879 application filed June 5, 1879.

To all whom it may concern:

Be it known that we, JOHN L. OOLES and DAVID H. (Jones, both of thecity, county, and State of New York, have invented a new and usefulImprovement in Cooling Mines, which improvement is fully set forth inthe following specification, reference being had to the accompanyingdrawing, which represents a mine in vertical section furnished with ourinvention.

Our invention consists in an apparatus for cooling mines, in which arecombined a coldair main, one or more flexible service-pipes leading fromthe main, and a portable tent or tents connected with the service pipeor pipes Within the mine, all of which will. be fully hereinafterdescribed in detail.

In carrying out our invention we put up in the first level of the mine,near the workingshaft, a refrigerator, A, suitable for cooling' air, andconnect to the inlet-orifice of this refrigerator a pipe, B, extendingto a point above ground, for supplying the same with surface air. Wealso connect to the refrigerator-- namely,,to its outlet-orificewhat weterm a cold-air main, 0, which we carry down into or through theworking-shaft and close at the lower end. This cold-air mainO, as wellas the air-supply pipe B, is intended to be placed in one corner of theworking-shaft, like the pipes of the pumps connected with the mine, toavoid obstruction.

In the respective drifts of the mine, two of which are shown in thedrawing, we arrange flexible or flexibly-jointed service-pipes D, (oneor more,) and connect one end of each of these pipes tothe cold-air main0, providing the same with a suitable cut-off valve, 6, while at theiropposite ends we connect each of the service-pipes to a tent, F, using asuitable coupling device for this purpose.

When more than one of the service-pipes D is used they are made ofdifferent lengths, thus terminating at different portions of the drift,and allowing the tents F to be put up at suitable distances apart fromeach other.

The tents F are made of oil-cloth or any other material impervious toair and water, and may be constructed in a variety of Ways, according tolocation and the uses to which they are to be put, thesame beingportable.

If required, a tent may be built at the end or either side ofa drift,and in that case we simply arrange a curtain at that point, as at g, atthe same time coupling this curtain with a service-pipe.

To facilitate the coupling of the tents F with the service-pipes D, weprovide these pipes with a flexible section, h, at their inner ends, theremaining portion of the pipes being of metal. If desired, theseservice-pipes may be made flexible throughout their whole lengths.

In this example we have shown one servicepipe, D, to each of the tentsF; but, if desired, two tents may be combined with a single servicepipe.

At a point beneath that at which the servicepipes D are connected to thecold air main (J, we provide the latter with a damper, I, arranged to beset by means of a rack, j.

If surface air is admitted to the refrigerator A, such air becomesrarefied, and thence passes downward into the main 0, and, entering theservice-pipes D, is supplied to the tents. These tents are thus keptcool, so that, for instance, workmen are enabled to perform their laborstherein with comfort, and inasmuch as the cold air is confined to thetents,

.a comparatively small volume of air is needed to produce the desiredefi'ect. A greater or less quantity of cold air may be supplied to theservice-pipes in a drift by adjusting the damper I accordingly. i Whatwe claim as new, and desire to secure by Letters Patent, is-- 1. In anapparatus for cooling mines, the combination of a cold-air main, one ormore flexible service-pipes leading from the cold-air main, and aportable tent or tents connected with the service pipe or pipes withinthe mine,

all substantially as and for the purposes set forth.

2. In an apparatus for cooling mines, the

combination, with a refrigerator, of a cold-air l we have hereunto setour hands and seals this main emanating from such refrigerator, one l 3dday of J une 1879. or more flexible service-pipes leading from the xmain, and a portable tent or tents connected 5' with the service pipe orpipes within the mine, o all constructed substantially as and for theWitnesses: purpose described.
